I think the major point made in the blog is that a change up is only as good as the fastball that sets it up. One without the other is not likely to strike fear in any good hitter.
I was trying to find out what defines a plus change-up. I've heard it said that a 10 mph differential is ideal, but any more can lead to decreased success. Movement is also key. It seems most crucial to know when to throw it, and when it's most likely to be effective. That is discussed in the piece and backed up with data. It would be really interesting to compare other pitchers who use the change up effectively (eg Santana or Hoffman) and see if the data is consistent.
